I'm working on a project with some guys to offer reusable plastic food containers in the metro Skyway systems. We have a challenge coming up with a dropbox, we envision something fancy like a Redbox video rental container or solid Fedex/UPS/USPS drop-off site with the 'self-locking' drop slot - but we know a prototype is going to be much more simple and less expensive.

Is anyone looking to practice their metal-, wood- or plastic-working and interested in partnering up with us to help design and construct at least a single prototype? We are looking forward to getting some ideas and seeing what people think of the idea!
